The customer manufactures components for the military industry. The contractor was tasked with drilling and boring large holes into 4150 steel (30 Rc) using a Mazak slant bed lathe with soluble coolant.
The customer needed a new solution that would increase the drilling speed of these large holes.
The solution of the T-A® GEN2 and the Opening Drill® successfully increased the speed of the hole making process. The solution also decreased cycle time for the customer.
